LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 349,110, datedSeptember 14,1886.

(No model.)

To all whom it may concern/.-

Be it known that I, CALVIN H. MArsrr, a citizen of the United States,residing at Oarson, in the county of Ormsby and State of N evada, haveinvented certain new and useful Improvements in Lamp-Burners; and Ido declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in lamp-burners, and especiallyto a device applied to the burner for the purpose of extinguishing thelight and closing the wick-tube when the wick is turned down, the'objectbeing to form an extinguishing device that shall be automatic in itsaction, and thus avoid the dangers arising from the too common method ofputting out these lights. by blowing down the chimney, as well as thedisagreeable smell arising from the charred wick when it is extinguishedby turning it down into the wicktnbe until the flame goes out.

A further object is to increase the brilliancy of the flame by giving anadditional current of air at each side of thewick-tnbe, which impingeson the edges of the wick and materially assists in keeping up a perfectcombustion at those points. The device also prevents oil from passingout of the lamp by capillary attraction through the wick when the lampis not in use, as the top of the wick being below the top of the tubethe oil drawn up by the wick cannot pass over, but must remain in thewick or return to the lamp.

This invention, therefore, consists in the construction, combination,and arrangement of the several parts of the burner and extinguishingdevice, as hereinafter described, and specifically stated in the claim,in order to effect the above-named objects in a better manner than bythe devices heretofore in use for accomplishing a similar result.

In the accompanying drawings, Figure 1 is a side view of a lamp-burnerprovided with my improvements. Fig. 2 is a top or plan view ofthe same.Fig. 3 is a vertical section,

with the wick down, on the line w 00, Fig. 2; and Figs. 4 and 5 showenlarged detail views of the extension-tube, the flap, and its operating devices.

A represents the body of the burner, constructed in the usual mannerwith the ordinary wick-tube B, having its edges rounded, so as to giveit an elliptical cross-section. A shaft, 0, provided with toothedwheels, is also employed to raise and lower the wick, and a vent-tube,D, for the escape of gas, is also supplied. These parts, being all oldand in common use, require no detailed description.

Surrounding the wick-tube and extending above it is a rectangular case,E, one side of which is cut away, as shown in Fig. 4, and its placesupplied by the flap a. This flap is pivoted in line with its lower edgein the ears I) I), and is free to swing across the opening in the caseso as to close it completely, but when in line with the side of thecase, to which it is'attached, fills the space out from the side of thecase E and sustains one side of the wick, so that when in this positionthe case acts as an extension of the wiclctube, the wick when it is tobe lighted being turned up until it projects above this extension.Attached to the outer side of the flap is an arm, 0, having an eye inits outer end, through which passes the free end of a spring, cl. Thisspring is attached to the side of the case, or at any other suitablepoint, and by its pressure on the arm has a tendency to cause the flapto close the opening in the case, which it does whenever the wick isturned down, as shown in Fig. 3; but when the wick is turned up the flapoccupics the position shown in Fig. 5, and, as before stated, forms oneside of the extension of the wick-tube.

The case E being rectangular in cross-section, and the wick-tube Brounded at the ends of its cross-section,it will be apparent that openspaces 6 a will be left at the corners. These spaces, beingopcn at thebottom, act as flues, causing a draft of air at each edge of the wick,making the combustion at these points more intense and preventing smoke.In applying these devices to lamps now in use it is only necessary toshorten the wick-tube a little and slip the case over it, the latter, ifproperly constructed, being retained in position by the pressure of itssides upon the sides of the wick-tube.

I am aware that it is not new to provide lamp-burners with aspring-operated hingeflap to act as an extinguisher; neither is it newto provide an outer case movable upon the wick-tube. I do not thereforeclaim those devices, broadly; but

Vhat I do claim, and desire to secure by Letters Patent, is as follows:

As an improvement in lamp-burners, the wick-tube having rounded corners,the wick, and devices for raising and lowering said wick, in combinationwith an outer case placed permanently upon the wick-tube, extendingabove
